Harmonic voltages and lighting equipment flicker caused by pumping station - measurements, analysis and mitigation

Abstract

This paper discusses cause and effect of harmonic voltages
and severe lighting equipment flicker that were observed by
low voltage end consumers in connection with the operation
of a pumping station connected to a 22 kV radial line of a
typical MV distribution network of a Norwegian utility. The
pumping station, consisting of three wound-rotor induction
motors rated at 1.75 MW, 6.6 kV, forms part of a local
medium-size hydro power scheme. The voltage disturbance
is a 7.harmonic (and partly 5.harmonic) component
fluctuating with a frequency of approximately 2 Hz,
resulting in considerable flicker problems in lighting
equipment at end customers, causing customer complaints.
